Can case fans be linked to GPU temp?

[Upgrayedd]

I've looked around and I can't find much. I'd like to link my case fans to GPU temp.

I've only ever seen CPU and mobo options in BIOS. My board is an ASRock OCFormula Z590.

The most promising thing I've found are the fan controllers and iCue software from Corsair. I'm just not sure if you can link fan speed to GPU temp using the corsair stuff. Does anyone know if you can?

If Fan Control can see your mobo & GPU sensors it can use a combined input from mobo temp and GPU temp to control case & GPU fan speeds. Interesting little program, and it's very flexible. But doesn't work on everything. Here's a Jayz2Cents video about the software.

Thanks! I also built in a new case yesterday and while the Bios fan settings are alright I wanted exactly that mix of CPU/GPU setup, gonna check out if its compatible with my setup.
I think I even watched this video when he posted it but I completely forgot about this software.

Argus Monitor can do this, I use it on machine with motherboard that has rubbish fan control otherwise and it's pretty good. https://www.argusmonitor.com/

I have seen this one mentioned. I haven't seen that github one.
Any idea how they compare?

There's a couple ways to do this. If your board has a temp sensor input (high end boards typically do) then you stick a sensor on your gpu die. You can also get a pwm gpu plug adapter and split that to use the pwm signal from your gpu.

My gpu does have a 4pin pwm connector on the end of it. FTW3 Ultra 3090. That method seems limited though, what happens when gpu fans stop?

That's up to you dude. You'd then use AB to set the profile.

Any fans using the same PWM signal will also stop (assuming the header shares signal with the 3090's onboard fans). In this case you could split your fans between PWM sources: Have some keyed to the GPU with its header, and others to CPU temp through the MB.

iCue does this. It allows different fans to be assigned to different sensors. I have my bottom rad fans tied to my GPU, top rad fans to CPU, and case fans set to ambient sensor I have on a header. There are a lot of complaints about iCue, but I have personally enjoyed the software myself.

A better temperature source for the case fans would be the motherboard sensor which accounts for heat coming from other components in the case that aren't the CPU (motherboard VRMs, MOS, storage devices, the graphics card, PSU, etc.).

That way when the load on the GPU is high but the CPU load isn't, you're still getting good airflow within the case.

All I know is the CPU and GPU aren't the only two sources of heat within my computers.

But that's just me, I know a lot of people have other ideas about how to cool their cases here.

The only use case for using gpu temp is if you're mining in my book.

Personally I use water temp but that's not applicable here.

I rely rather heavily on the KISS principle, so simply made a straightforward suggestion based on assumptions I could be reasonably confident were correct. Better ways to do it? Probably. But CPU and GPU are the two largest sources of heat, so basing fan profiles around their temp values seems logical to me.

I own several ASUS motherboards and they all have a motherboard/system thermal sensor so keying the case fans off of that is super simple. It's not like it's a complicated procedure or obscure setting.

The point of a case fan is to remove hot air from the interior of the PC case, heat generated from whatever combination of components in various states of usage.

Anyhow it's clearly time for me to bow out of further PC cooling discussions here.

Best of luck to OP.

Hi, is you case a Fractal Design Define R4? Maybe you can connect your front mid case fan to the evga PWM. So when in load, it will rev up with your GPU fans and generate a cool airflow to the backplate of the 3090 which has contact with the GDDR6X and can reach very high temps.

Ah that's my old case. This is a new PC I'm trying to tune. Lian Li lancool2, nhd15, ft3 3090, asrock ocf z590, 11700k, 2x16GB 3600 c16 at clocked to 3800, all cpu and case fans are 3000rpm noctuas. The one fan header on the gpu and single case fan that sits at gpu height would be the cheapest method, I already use msi ab. The memory only ever gets to around 82C even when it mined on it.
More than one fan would be really nice though.

It used to be in my mining rig but it's gaming now. It puts out much more heat than my cpu though that's why I want the case fans linked to it instead of the cpu.

I tried hooking two iPPC 140s to my 3070Ti using a splitter after seeing it drive a little Thermalright 120mm fan. It didn't work. But maybe it would have worked if I would have plugged it into a separate powered hub.

The easy compromise is figure out the average cpu temp vs gpu temp in a swath of your games and dial your pwm to move on the cpu but also add in a couple seconds of delay so its not popping each time you open a browser or something etc. Then the fans will ramp only after a couple seconds of sustained load.

Too bad this isnt supported in BIOS , many of the cases now have bottom intake fans that throw air directly to the GPU.

 

[freeagent]

You could try setting the designated header of your choice to scale with the chipset temps instead of the CPU. It works ok.

If Fan Control can see your mobo & GPU sensors it can use a combined input from mobo temp and GPU temp to control case & GPU fan speeds. Interesting little program, and it's very flexible. But doesn't work on everything. Here's a Jayz2Cents video about the software.

Bumping this. Great and free solution.

If you're going to use P12s, there are models with sensors (PST). I'd suspect you could place those sensors on various locations. Not the best approach but I don't know.

PST stands for PWM Sharing Technology, a pass-through system that allows you to daisy-chain several fans on the same PWM signal. There are no temp sensors in P12s.

This ^^, been using it for a good time now and never gave any issue's.
